MECHANICALLY AND ELECTRICALLY INTEGRATED ROTARY ELECTRIC MACHINE

摘要

In a mechanically and electrically integrated rotary electric machine, a motor portion and an inverter portion are inserted inside a cylindrical frame. The motor portion has a plurality of coils. The inverter portion has a plurality of switching elements. The coils and the switching elements are electrically connected by a connector. The connector has: an end portion connector that distributes sinusoidal electric currents from the switching elements to the respective coils; and a plurality of axial connectors that direct the sinusoidal electric currents from the switching elements to the end portion connector. The end portion connector is disposed on an end portion of the motor portion near an output shaft. The axial connectors are disposed parallel to an axial direction of the frame so as to pass from the switching elements through a mounted region of the motor portion.
